Why am i so cynical about people in my life?

It's understandable it seems like you've been through a lot being neglected. A lot of this is just your mind set and i really believe it starts with trusting your therapist tell her about the fact that you feel like she doesn't care i bet you she really really does. It's just something you will have to slowly break through it's not one thing you can just do to stop feeling this way it's a process that you will just have to work through with a therapist.
